Which of these is NOT a reason for mitosis in humans?
to grow
to make sperm and egg cells for reproduction
to heal
to replace dead cells
Answers
Answer:
to heal..
Explanation:
Answer: To make sperm and egg cells for reproduction
Explanation:
Cell division happens in humans and most other animals by mitosis and meiosis. When a cell divides by way of mitosis, it produces two clones of itself, each with the same number of chromosomes. When a cell divides through meiosis, it produces four cells, called gametes. Gametes are also called sperm in males and eggs in females.
Unlike in mitosis, the gametes produced by meiosis are not clones of the original cell, because each gamete has exactly half as many chromosomes as the original cell.
In healing and growth, mitosis occurs beacuse the body clones cells to produce more of the exact same kind of that body part.

a driver needs to make a delivery to an office that is 30 km away. The driver has traveled for 45minutes west down a straight road at 50km/h. A has the driver traveled far enough to the office? support your response. B assume the driver has gone far enough and is traveling on the correct road. If he has not yet seen the business, what should he do to make the delivery? Explain your reasoning
Answers
The speed of the driver = 50 km/h
Distance from office = 30 km
Time travelled by driver = 0.75 h
Speed = Distance / time
∴ Distance = Speed * time
= 50 * 0.75 = 37.5 km
the distance travelled by the driver 37.5 km is greater than the distance from the office 30 km
he had already driven enough to reach the place

2. Hanging clothes -
3. Walking -
4. Feeding the stray animals -
5. Using back page of paper -
6. Using fan -
7. Watering the plants -
8. Sweeping -
Answers
1. Using a glass when brushing teeth: By using a glass instead of leaving the tap running while brushing our teeth, we can conserve water. Freshwater is a finite resource, and reducing unnecessary water usage is essential for preserving our water supplies and ensuring their availability for both humans and the natural environment.
2. Hanging clothes: Opting to hang clothes to dry instead of using a dryer not only saves energy but also reduces greenhouse gas emissions. Clothes dryers consume a significant amount of electricity, and by utilizing natural methods like hanging clothes, we can contribute to reducing our energy consumption and lowering our carbon footprint.
3. Walking: Walking instead of using vehicles for short-distance travel offers multiple benefits. Firstly, it helps reduce air pollution by decreasing the emission of harmful gases from vehicles. Secondly, walking promotes personal health and well-being, as it is a form of physical exercise. Lastly, choosing to walk reduces traffic congestion and saves fuel.
4. Feeding stray animals: Feeding stray animals is an act of compassion and kindness. By providing food for stray animals, we help prevent their starvation and promote their overall welfare. It also reduces their need to hunt for food in natural habitats, preserving the delicate balance of local ecosystems.
5. Using the back page of paper: Utilizing both sides of a piece of paper helps reduce paper waste and conserves valuable forest resources. Paper production involves cutting down trees, and by maximizing the use of each sheet, we minimize the number of trees required to produce paper products.
6. Using a fan: Using a fan instead of an air conditioner helps reduce energy consumption and lowers greenhouse gas emissions. Air conditioners consume a significant amount of electricity, and by using fans to circulate air and provide cooling, we can contribute to conserving energy resources and mitigating the impact of climate change.
7. Watering the plants: Watering plants is essential for their growth and well-being. By providing them with adequate water, we support their ability to photosynthesize, produce oxygen, and contribute to a healthy ecosystem. Additionally, practicing responsible watering techniques, such as using watering cans instead of hoses, helps conserve water resources.
8. Sweeping: Sweeping instead of using a leaf blower or a hose to clean outdoor spaces reduces energy and water consumption. Leaf blowers and hoses consume significant amounts of electricity and water, respectively. Sweeping not only saves resources but also minimizes noise pollution and prevents soil erosion caused by high-pressure water flow.
Engaging in these activities of conserving natural resources demonstrates our commitment to environmental stewardship and sustainable living. By making conscious choices in our daily lives, we can contribute to the preservation and protection of the Earth's ecosystems for the benefit of current and future generations.

1.) How does air move during sea breeze?
2.) From where does the wind blow during the land breeze?
3.) What time of the day does the sea breeze occur? (night time or day time)
4.) Which heats faster, land or sea?
5.) Compare the direction of air in sea breeze and land breeze.
Answers
PLS MARK ME AS BRAINLIEST
1.) As a result, warm air rises. Therefore, the warmer air over the land surface is rising. As the warm air over the land is rising, the cooler air over the ocean is flowing over the land surface to replace the rising warm air.
2.) a cool wind that blows from land to water. On clear, calm evenings, temperature differences between a body of water and neighboring land produce a cool wind that blows offshore. This wind is called a "land breeze".
3.) While sea breezes occur during the day, land breezes occur at night.
4.) Since land absorbs more solar radiation the land surface retains more heat as do the vegetation for energy. Thus, land surfaces warm more quickly than water.
5.) Sea breeze carries increased moisture, which it absorbs while blowing over a water body. A Land breeze is drier since it has no opportunity to absorb water from any source. Lastly, the sea breeze moves from the sea towards a land body. A Land breeze moves from land toward a water body, generally a sea or ocean.
Answer: 1.) During a sea breeze, the air moves from the sea towards the land. During the day, the land heats up faster than the sea. As a result, the air above the land becomes warmer, and it rises. The cooler air from the sea moves towards the land to replace the rising warm air, resulting in a sea breeze.
2.) During the land breeze, the wind blows from the land towards the sea. At night, the land cools faster than the sea. The air above the sea remains warmer and rises, and the cooler air from the land moves towards the sea, resulting in a land breeze.
3.) The sea breeze occurs during the daytime.
4.) Land heats up faster than water. This is because water has a higher specific heat capacity than land. Specific heat capacity refers to the amount of energy required to increase the temperature of a substance. Water requires more energy to heat up compared to land, which is why it heats up slower than land.
5.) During a sea breeze, the direction of air is from the sea towards the land. During a land breeze, the direction of air is from the land towards the sea.
Explanation:
The theory of evolution has changed over time. Initially, Lamarck believed that organisms developed traits in response to a changing environment to improve their chances of survival. Later Darwin proposed that organisms that already possessed traits suitable to a changing environment were more likely to survive and reproduce.
Which of the following does not explain why the theory of evolution has changed?
A. Lamarck’s theory was discarded when new scientific information became available.
B. Darwin collected empirical evidence to support that organisms with favorable traits survived and reproduced.
C. The theory of evolution became a scientific law after much debate and confirmation in the scientific community.
D. Other scientists such as Peter and Rosemary Grant have collected additional empirical evidence that supports Darwin’s findings.

What best describes ribosomes?
Answers
Ribosomes are cellular structures that synthesize proteins from amino acids. They are composed of ribosomal RNA and proteins and are found in both prokaryotic and eukaryotic cells.
Ribosomes are essential for gene expression and cell growth. They can be free in the cytoplasm or bound to the endoplasmic reticulum or the nuclear envelope.
An example of a ribosome function is the translation of a messenger RNA (mRNA) sequence into a polypeptide chain. The ribosome reads the mRNA codons and matchesthem with the corresponding transfer RNA (tRNA) anticodons that carry the amino acids. The ribosome then forms a peptide bond between the amino acids and releases the tRNA. This process continues until the ribosome reaches a stop codon on the mRNA and terminates the protein synthesis.
Answer:
A ribosome is a intercellular structure made of RNA and protein
